PAINT SHIELD.

Applicationl led April 4,

This invention relates generally to paint shields and more particularlyto shields for use in the painting of vehicle bodies.v

One of the essential objects of the present invention is the provisionof a paint shield so constructed and arranged that when it is applied tothe vehicle it enables painter other finishing liquid to be quicklyapplied with accuracy to the body.`

Another object is the provision of a paint shield which may be quicklyand easily attacliable in a window opening for applying paint upon awindow frame, the arrangement being such as to prevent the flowing ofthe paint beyond certain predetermined points, thereby insuring a neatand accurately painted frame.

In the accompanying drawings Figure 1 is a perspective View of the frontof the paint applying apparatus;

Figure 2 is a perspective view of the back portion thereof;

Figure 3 is a sect-ion taken on line 3-3 of Figure 1; i

Figure 4 is a section taken on line 4 4 of Figure 1.

In the accompanying drawings wherein like characters of referenceindicate like parts, the numeral v1 indicates generally a saint shieldcomprising a main frame member 2 preferably of retangular formationhaving the integrally connected inside portions a, a', b, b. Extendingacross the frame member from one to the other of the side portions a anda are cross bars 3 and 4 v integrally connected thereto and alsoconnected to each other by means of the longitudinally extending bar 5.

Preferably the frame member 2 is of channel shaped formation with thechannels facing outwardly. As shown the outer faces of the 'baseportions of the channels have secured thereto a plurality of spaced leafsprings 6 which vare adapted to yieldably space a rectangular springmetal frame 7 from the main frame member 2. Preferably guide members 8are provided which Vare rigidly secured to the spring metal frame 7 andwhich are adapted to slide through openingsprovided at spaced intervalsin the main frame 2.

As shown, the leaf springs 6 are secured to the main frame intermediatethe bowed portions thereof and are provided withflat 1927. Serial No.180,977.v

end portions 9 for engaging the spring metal frame 7. Preferably nuts 10are screw threaded upon the ends of the guide members 8 and are adaptedlto seat within the channel portions of the main frame when theapparatus is not in use.

As shown in Figure 2 there is provided a sheet metal panel 11 of a sizesmaller than that of the main and spring metal frames and adapted to bespaced outwardly therefrom. Rigidly secured to the panel 11 are a pairof shafts 12 and 13 extending through openings in the cross bars 3 and 4respectively. The end portions of each shaft is provided with aflattened portion to which is pivotally secured the bifurcated endportion of a cam lever 14 having the cam surfaces 15 for engaging theraised portion 16 of each cross bar. Preferably each shaft 12 and 13 hassleeved thereon a coil spring 17 for normally holding the panel 11spaced from the frame 2.

Slidably secured yto the outer edge portions of the panel 11 are backstrips c, c and d, al

which are adapted to be moved radially outward after the shield has beenplaced in position in a window opening. For operating VVthese stripsthere is provided a single control toggle lever 18 pivotally secured tothe panel 11 centrally thereof and having the handle 19 rigidly securedthereto. `To each end of they toggle lever 18is piv otally secured alink 2O which in turn is pivotally connected to a transversely extendingflexible strapv 21.

vFiach strap 21 is provided at its ends with headed. studs 22 one of'which is pivotally secured to the strip C and the other to the strip C.Likewise there are provided links l23 pivotally secured adjacent the endpor-v tions. oftlie straps 21 and which are also provided with studs 24engaging the strips d, rl. A

strips relative to the panel and for slidably securing the same'thereto, the panel is provided with a plurality of slots through whichthe studs 22 and 24 extend, the headed portions of the studs beingadapted to contact with the outer face of the panel. Likewise there areprovided studs 26 which are adapted to slide in slots 27 for guiding thestraps 20 when thev toggle is operated.

For providing forthe adjustment of the While the present apparatus isparticu- Y larly adapted to be used in connection with the painting ofthe window frames of automobiles it may of course be used for apply* inga border of paint to any type of window frame. In operation and assumingthat a border is to be painted upon the frame portion E shown in Figure3, the main frame is so positioned that the spring metal frame 7contacts at all points with the body panel above the frame E. At thesame time the panel 11 will be positioned far enough within the frame Efor allowing the back plates 'to slide laterally outward and engagebehind `the edges of the inturned marginal frame G when the toggle leveris actuated.

The cam levers 111 are then ope ated to move the main frame 2 toward thepanel 11 so that the springs 6 will urge the spring metal frame 7 firmlyagainst the body panel F, thus insuring a tight joint.

Paint may now be sprayed around the entire surface of the frame Ewhereupon the shield may then be quickly removed by simply operating thecam levers 14 and turning the toggle lever handle 18. The frame 7 isadapted to Contact with the panel portion F of the vehicle body in sucha manner that the portion of the panel adjacent the frame E is entirelyprotected thereby so that the paint is permitted to coat only the frameE of the vehicle, thus insuring a neat and accurately painted border.

During the painting operation a spray gun is preferably used and this isadapted to be actuated by'an operator standing outside of the vehiclebody. The operator will direct the spray of paint within the open framemember 2 and will move the gun entirely around the window openingrso asto paint the desired border upon the vehicle body.

It should be stated that the straps 21 are so constructedv as to allowfor the flexing thereof when the toggle lever 18 is operated, therebyinsuring the inward movement of the back plates c and e with the platesCZ and ci.

It found desirable a shaft 28 may be secured to the panel 11 having itsfree end extending through an opening in the rod 5. As shown, a coilspring 29 is preferably sleeved thereon between the panel 11 and the rod5 for cooperating with the springs 17 to retain the main frame and panelin spaced relation. If desired corner plates 30 may be provided upon thepanel 11, these plates acting as reinforcing members and alsoconstituting means for supporting the shield when not in use.

While the main frame may be composed of any suitable material wepreferably construct the same of aluminum. Likewise coil springs or anyother type of springs may be used in place of the leaf springs 6 betweenthe main frame and the spring metal frame. It will also be apparent thatour paint shield may be so constructed and proportioned as to lit anytype of window openings regard less of the shape thereof.
